Pest? ID

[Andrew_B]

Have another weird looking thing for you guys
It's growing out of a group of Zoas. It doesn't move but just grows longer. Growing real slow for maybe 2 months now. Is it come kind of hitchhiking coral? It's growing at about the same rate as some of my corals do.

If its green and fuzzy it's a type of macroalgae. Forget the name though.

Good call, googled fuzzy macro algae and got Neomeris annulata.

Thats it. I only have 1 piece of it. Apparently a hard algae to get, keep... and get rid of if it becomes an infestation. Requires high calcium levels
